But the Callins is 25 volts.

So? You didn't specify. You said "What use is a 300 uF non-polar 'lytic?"

I imagine the Amazon cap could be used in audio applications. It may even
have lower distortion. It is certainly intended to carry amps of current,
and might even be used in high power aplications where the original
collins would fail.

The Amazon is brand new, where the collins has probably dried out by now.
